Browse categories step by step. Call with no params to see Karat options (Level 1). Pass parent_id to see its children (Level 2=Collection or Level 3=Style). Only Level 3 IDs work with get_category_products.
AI agents call get_categories to retrieve information from Arham Jewellers MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries category hierarchy information with no side effects. It is a straightforward read operation that allows browsing of product categories in a structured manner, similar to a GET request in REST APIs. No data is created, modified, deleted, or external operations are triggered.
From the tool's definition Tool description states 'Browse categories step by step' and enables retrieval of hierarchical category data. No modification, deletion, or execution of commands occurs. The tool 'pass[es] parent_id to see its children', indicating data retrieval only.

Register the Arham Jewellers MCP Server MCP server in PolicyLayer and add a rule for get_categories: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Arham Jewellers MCP Server. Nothing to install.
get_categories is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_categories rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_categories. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
